Member of Technical Staff (Software Engineer, Infrastructure)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Member of Technical Staff (Software Engineer, Infrastructure) based in the United States. This role focuses on building and operating the foundational infrastructure behind real-time search, retrieval, model serving, and agent workloads. You will tackle complex infrastructure challenges that span multiple technical domains rather than being limited to a single platform area. The position offers opportunities to own production systems end to end, from architecture and implementation through reliability and ongoing operations. You will improve performance, scalability, availability, and cost efficiency across both online traffic and background workloads. A key part of the role involves identifying gaps between existing platforms and creating shared abstractions, automation, and tooling that make infrastructure safer and easier to use. You will also help shape technical direction, lead high-impact programs, and collaborate with infrastructure, product, AI, and security teams. This is an excellent opportunity for an experienced infrastructure engineer who thrives on ambiguity, cross-cutting problems, and high-impact technical ownership
